The formula is spot on - easy to spread, opaque, and dries relatively quickly. The brush is the best on the market - wide and evenly distributes product. There are so many colors to choose from. This is simply the best product on the market.

I find OPI to be the best nail polish brand on the market - and even though it runs about $10 a bottle, I think it's totally worth it. It may be more expensive than some other brands, but beats having to repaint your nails every day or going to the salon for a $25 manicure!

My all time favourite brand of nail polish, whether I do my own nails or go to get my nails done, I always pick and OPI colour.

Great quality of nail polish. They have great color tho

I love the quality of OPI Nail Polishes. They glide on smoothly, don't leave any clumps or streaks and they are truly true to colour. When adding a base and top coat, it's very long lasting.

I have a shamefully large nail polish collection. I might have had over 2,000 bottles at one point last year. Yeah... It's a serious problem. But! I know a lot about nail polish. And OPI is a brand that I keep going back to over and over again. Rarely am I disappointed by the OPI formula. Of course I don't love every colour they put out but I definitely almost always love the formula. I love the brush, consistency, finish and staying power. OPI can last up to a week on me without chips when worn with a good top coat. I will always love OPI.

My favorite colours are probably Funny Bunny, Rumple's Wiggin, Mermaid's Tears, Incognito In Sausalito, Anti-Bleak, The One That Got Away and Black Cherry Chutney.

I can't say enough good things about OPI. The nail polishes glide on smoothly, the colours are rich and they wear so well. I'm on week two and not the slightest show of wear. The ones with sparkles are the most durable.

I love OPI nail polish. Amazing color selection, long lasting, great shine. One of my favorites!

I don't always wear nail polish but when I do I love wearing opi because there are so many colors it goes on smoothly and doesn't chip

I love OPI nail polish. I like getting my nails done and I have a lot of nail polish to do my own nails. When I get my nails done it is always my go to brand as I know it is reliable and long lasting. I also enjoy purchasing
OPI as there are many vibrant colors and its nice to have color on your nails! A must buy... you will have no regrets!
